“…A diverse range of cognitive tasks, mainly drawn from the neuropsychological literature, has been used to assess objective recovery. Popular tasks include the mini mental state examination (Breslin, Reid, Mirakhur, Hayes, & McBrien, 2001), digit-symbol substitution (Chung et al, 1990;Wandel et al, 1995), maze tracing (Kestin, 1990), tracking (Moss, Hindmarch, Pain, & Edmonson, 1987), digit span (Baykara, Sahin, & Toker, 2001;Münte et al, 2001) and other aspects of memory (N'Kaoua, Veron, Lespinet, Claverie, & Sztark, 2002;Rundshagen, Schnabel, & Schulte am Esch, 2002) and choice reaction time (Haavisto & Kauranen, 2002;Pollard et al, 1994;Scott, Whitwam, & Wilkinson, 1983;Thompson, Rushman, Fox, Lloyd, & Atcheson, 2002). Performance on driving simulators has also been studied (Ward, Imarengiaye, Peirovy, & Chung, 2005).…”
